Interstitial HDR brachytherapy (HDR-BT) in early stage mobile tongue cancers in young patients – Gliwice experience
PURPOSE In early stage mobile tongue cancer radical radiotherapy offers good local control and organ preservation, which is especially important in the group of young patients. In our department, for many years HDR-BT has been performed in mobile tongue cancers as a sole treatment or as a "boost" with EBRT. The aim of the study was to show our experience with HDR-BT in early stage mobile tongue...
متن کاملPractical considerations for prostate HDR brachytherapy.
PURPOSE A process for prostate high-dose-rate (HDR) brachytherapy was developed and implemented successfully in the community hospital setting. The practical aspects of the program are reviewed and may serve as a foundation for clinics interested in offering this clinical service. METHODS AND MATERIALS A generic needle distribution geometry was established to accommodate target volumes of var...
متن کاملAutoactivation of source dwell positions for HDR brachytherapy treatment planning.
The most accurate classical dose optimization algorithms in HDR brachytherapy strongly depend on an appropriate selection of source dwell positions which fulfill user-defined geometrical boundary conditions which are relative to patient anatomy. Most anatomical situations, such as for prostate and head and neck tumors, are complex and can require geometries with 5-15 catheters with 48 possible ...
متن کاملA new CT prostate segmentation for CT-based HDR brachytherapy
High-dose-rate (HDR) brachytherapy has become a popular treatment modality for localized prostate cancer. Prostate HDR treatment involves placing 10 to 20 catheters (needles) into the prostate gland, and then delivering radiation dose to the cancerous regions through these catheters. These catheters are often inserted with transrectal ultrasound (TRUS) guidance and the HDR treatment plan is bas...
متن کاملComparison of two planning systems for HDR brachytherapy gynecological application
PURPOSE This report compares the Nucletron NPS and PLATO planning system for patients treated for cervix cancer. MATERIALS AND METHODS This study compares calculations generated using the older NPS (version 11.43) planning system and the more recent PLATO (version 14.1) system for two cases: 1) a single dwell position and 2) an actual patient application using a tandem and ovoid. RESULTS Fo...
